Importance du concept "made-in" dans un contexte d’évaluation multi-attributs/multi-produits : effet modérateur des variables de personnalité

Le traité du libre-échange entre les États-Unis et le Canada, l'intégration économique des 12 pays d'Europe et les changements politiques et socio-économiques survenus dans les pays de l'Est sont des exemples d'événements qui ont marqué la fin de la dernière décennie. Ces événements ont pour effet de modifier les règles du jeu de la concurrence internationale en matière de commerce et d'affecter directement les activités des entreprises oeuvrant aussi bien dans les marchés étrangers que domestiques. La firme doit avoir la capacité de connaître davantage le comportement de la clientèle-cible et celui de la concurrence afin de mieux adapter ses stratégies de marketing à cette nouvelle réalité. Les décisions auxquelles les exportateurs et les producteurs locaux ont toujours fait face ont trait à des variables stratégiques, entre autres le prix, le nom de la marque, la promotion, la distribution, le service et le lieu de fabrication ("Made-In"). Cette dernière variable a toujours été d'une grande importance pour les firmes ayant des opérations étrangères; en effet, elle touche deux aspects décisionnels à savoir, le coût d'installation des unités de production dans un pays étranger et la réputation ou l'image de ce dernier chez le consommateur. La présence de produits importés à côté des produits domestiques augmente l’éventail de choix du consommateur. Cependant, sa préférence pour un produit par rapport à un autre dépend de plusieurs éléments, soit des facteurs reliés au produit comme son prix compétitif ou sa qualité supérieure, ou bien des facteurs de personnalité, comme le besoin de prestige et d'appartenance.

Le concept des principes féminin et masculin appliqué à l'orientation

Depuis l'avènement de la révolution industrielle, la société se transforme à un rythme effarant. Pour ne donner que quelques exemples, pensons à la place qu'occupent maintenant les jeunes sur le marché du travail, à la hausse de la scolarisation, mais aussi, du décrochage scolaire, à la montée de la violence, de la pauvreté et du racisme, au marché du travail qui se veut de plus en plus exigeant, au taux de chômage élevé et nous aurons un aperçu des nombreux bouleversements qui ébranlent la société. Cette période de grande transformation est à l'image de celle que peut vivre l'être humain lors de ses étapes de transition, c'est-à-dire qu'elle est souvent difficile à traverser, suscitant le doute, la peur, la résistance au changement. Plusieurs auteurs ont exploré les causes possibles de la stagnation et de l'impuissance à trouver des solutions vraiment efficaces aux nombreux défis qui sont posés. Parmi les réponses proposées, la notion des principes féminin et masculin "refait surface" et apporte un éclairage que l'on pourrait qualifier de philosophique ou de spirituel; c'est cette vision de la vie et de l'être humain que nous allons présenter dans le cadre de cet essai. C'est ainsi qu'après avoir établi un bref constat des malaises collectifs "de l'heure", nous présenterons plus spécifiquement individuels et la notion des principes féminin et masculin en utilisant une perspective historique qui nous fera remonter jusqu'à leur origine. Nous appliquerons ensuite ce concept à l'orientation et nous verrons comment il peut être utilisé à l'intérieur de la pratique carriérologique. Pour ce faire, nous présenterons en premier lieu notre cadre de référence qui s'appuie sur le courant cognitif développemental ainsi que sur la notion de résistance au changement. Nous traiterons ensuite plus particulièrement du diagnostic, du traitement et de la finalité qui sont trois voies possibles à emprunter en regard de ce concept. Enfin, nous discuterons brièvement du rôle du conseiller d'orientation, et ceci, aux niveaux individuel et collectif. Les enjeux de l'orientation étant particulièrement liés à l'expression de soi, nous tenterons de démontrer la pertinence pour l'être humain d'enrichir son répertoire de comportement en reprenant contact avec l'autre en soi: le masculin ou le féminin.

Three-dimensional, in-silico breast phantom for multimodality image simulations

We report on the construction of anatomically realistic three-dimensional in-silico breast phantoms with adjustable sizes, shapes and morphologic features. The concept of multiscale spatial resolution is implemented for generating breast tissue images from multiple modalities. Breast epidermal boundary and subcutaneous fat layer is generated by fitting an ellipsoid and 2nd degree polynomials to reconstructive surgical data and ultrasound imaging data. Intraglandular fat is simulated by randomly distributing and orienting adipose ellipsoids within a fibrous region immediately within the dermal layer. Cooper’s ligaments are simulated as fibrous ellipsoidal shells distributed within the subcutaneous fat layer. Individual ductal lobes are simulated following a random binary tree model which is generated based upon probabilistic branching conditions described by ramification matrices, as originally proposed by Bakic et al [3, 4]. The complete ductal structure of the breast is simulated from multiple lobes that extend from the base of the nipple and branch towards the chest wall. As lobe branching progresses, branches are reduced in height and radius and terminal branches are capped with spherical lobular clusters. Biophysical parameters are mapped onto the complete anatomical model and synthetic multimodal images (Mammography, Ultrasound, CT) are generated for phantoms of different adipose percentages (40%, 50%, 60%, and 70%) and are analytically compared with clinical examples. Results demonstrate that the in-silico breast phantom has applications in imaging performance evaluation and, specifically, great utility for solving image registration issues in multimodality imaging.

Le concept d'expérience chez John Dewey et la problématique de l'éducation morale

L'éducation morale peut-elle répondre au défi et au besoin d'une éthique personnelle et sociale? Comment l'école peut-elle mettre en branle un processus de socialisation chez les jeunes? Permet-elle d'éclairer, d'élargir et d'approfondir le contenu social des enjeux éthiques chez l'enfant quand celui-ci est aux prises constamment avec le devoir du rendement et des notes? La pédagogie de l'enseignement moral telle que vécue dans nos écoles ouvre-telle les portes à la socialisation ou au narcissisme et à l'individualisme? Y a-t-il, en fait, entre l'organisation scolaire et l'organisation sociale, une continuité grâce à laquelle la formation morale à l'école permet au jeune de s'engager dans le processus social tout en développant des connaissances et des aptitudes nécessaires pour comprendre les enjeux éthiques collectifs et proposer des pistes de solutions? Pour favoriser cette continuité, l'organisation scolaire ne devrait-elle pas être à l'image de l'organisation sociale? Ultimement, quel lien existe-t-il entre l'école québécoise et notre société? Ce rapide survol de la problématique de l'éducation morale nous permet de distinguer actuellement trois niveaux d'interrogation: la conception de l'être humain sous-jacente aux programmes, la finalité de l'enseignement dans les écoles du Québec, ainsi que son enjeu social. Soulever ainsi cette problématique nous aide à mieux réfléchir sur la situation et à proposer des pistes de solutions pour faire de l'éducation morale une théorie et une pratique toujours plus conformes aux expériences individuelles et sociales de chez nous. C'est à partir de ce questionnement global que le philosophe et pédagogue américain John Dewey (1859-1952) nous semble très pertinent. Face à la problématique de l'éducation morale au Québec, la référence spécifique à John Dewey nous semble crédible pour plusieurs raisons. […]

A Comparison of Geo-tagging in Mobile Internet Browsing Applications on iOS and Android.

Nowadays there is almost no crime committed without a trace of digital evidence, and since the advanced functionality of mobile devices today can be exploited to assist in crime, the need for mobile forensics is imperative. Many of the mobile applications available today, including internet browsers, will request the user’s permission to access their current location when in use. This geolocation data is subsequently stored and managed by that application's underlying database files. If recovered from a device during a forensic investigation, such GPS evidence and track points could hold major evidentiary value for a case. The aim of this paper is to examine and compare to what extent geolocation data is available from the iOS and Android operating systems. We focus particularly on geolocation data recovered from internet browsing applications, comparing the native Safari and Browser apps with Google Chrome, downloaded on to both platforms. All browsers were used over a period of several days at various locations to generate comparable test data for analysis. Results show considerable differences not only in the storage locations and formats, but also in the amount of geolocation data stored by different browsers and on different operating systems.

Deep convolutional neural networks for semantic video object segmentation

In this thesis, we propose to infer pixel-level labelling in video by utilising only object category information, exploiting the intrinsic structure of video data. Our motivation is the observation that image-level labels are much more easily to be acquired than pixel-level labels, and it is natural to find a link between the image level recognition and pixel level classification in video data, which would transfer learned recognition models from one domain to the other one. To this end, this thesis proposes two domain adaptation approaches to adapt the deep convolutional neural network (CNN) image recognition model trained from labelled image data to the target domain exploiting both semantic evidence learned from CNN, and the intrinsic structures of unlabelled video data. Our proposed approaches explicitly model and compensate for the domain adaptation from the source domain to the target domain which in turn underpins a robust semantic object segmentation method for natural videos. We demonstrate the superior performance of our methods by presenting extensive evaluations on challenging datasets comparing with the state-of-the-art methods.

A contribution to semantic description of images and videos: an application of soft biometrics

Humans have a high ability to extract visual data information acquired by sight. Trought a learning process, which starts at birth and continues throughout life, image interpretation becomes almost instinctively. At a glance, one can easily describe a scene with reasonable precision, naming its main components. Usually, this is done by extracting low-level features such as edges, shapes and textures, and associanting them to high level meanings. In this way, a semantic description of the scene is done. An example of this, is the human capacity to recognize and describe other people physical and behavioral characteristics, or biometrics. Soft-biometrics also represents inherent characteristics of human body and behaviour, but do not allow unique person identification. Computer vision area aims to develop methods capable of performing visual interpretation with performance similar to humans. This thesis aims to propose computer vison methods which allows high level information extraction from images in the form of soft biometrics. This problem is approached in two ways, unsupervised and supervised learning methods. The first seeks to group images via an automatic feature extraction learning , using both convolution techniques, evolutionary computing and clustering. In this approach employed images contains faces and people. Second approach employs convolutional neural networks, which have the ability to operate on raw images, learning both feature extraction and classification processes. Here, images are classified according to gender and clothes, divided into upper and lower parts of human body. First approach, when tested with different image datasets obtained an accuracy of approximately 80% for faces and non-faces and 70% for people and non-person. The second tested using images and videos, obtained an accuracy of about 70% for gender, 80% to the upper clothes and 90% to lower clothes. The results of these case studies, show that proposed methods are promising, allowing the realization of automatic high level information image annotation. This opens possibilities for development of applications in diverse areas such as content-based image and video search and automatica video survaillance, reducing human effort in the task of manual annotation and monitoring.

A non-contrast self-navigated 3-dimensional MR technique for aortic root and vascular access route assessment in the context of transcatheter aortic valve replacement: proof of concept.

OBJECTIVES: Due to the high prevalence of renal failure in transcatheter aortic valve replacement (TAVR) candidates, a non-contrast MR technique is desirable for pre-procedural planning. We sought to evaluate the feasibility of a novel, non-contrast, free-breathing, self-navigated three-dimensional (SN3D) MR sequence for imaging the aorta from its root to the iliofemoral run-off in comparison to non-contrast two-dimensional-balanced steady-state free-precession (2D-bSSFP) imaging. METHODS: SN3D [field of view (FOV), 220-370 mm(3); slice thickness, 1.15 mm; repetition/echo time (TR/TE), 3.1/1.5 ms; and flip angle, 115°] and 2D-bSSFP acquisitions (FOV, 340 mm; slice thickness, 6 mm; TR/TE, 2.3/1.1 ms; flip angle, 77°) were performed in 10 healthy subjects (all male; mean age, 30.3 ± 4.3 yrs) using a 1.5-T MRI system. Aortic root measurements and qualitative image ratings (four-point Likert-scale) were compared. RESULTS: The mean effective aortic annulus diameter was similar for 2D-bSSFP and SN3D (26.7 ± 0.7 vs. 26.1 ± 0.9 mm, p = 0.23). The mean image quality of 2D-bSSFP (4; IQR 3-4) was rated slightly higher (p = 0.03) than SN3D (3; IQR 2-4). The mean total acquisition time for SN3D imaging was 12.8 ± 2.4 min. CONCLUSIONS: Our results suggest that a novel SN3D sequence allows rapid, free-breathing assessment of the aortic root and the aortoiliofemoral system without administration of contrast medium. KEY POINTS: • The prevalence of renal failure is high among TAVR candidates. • Non-contrast 3D MR angiography allows for TAVR procedure planning. • The self-navigated sequence provides a significantly reduced scanning time.

Invención e innovación tecnológica en el ciclismo en España a través de la documentación de patentes : 1826-1929

El objetivo general de esta investigación consiste en sacar a la luz un conjunto de documentos, los documentos de patentes presentadas en España, sobre un tema concreto, la bicicleta y el ciclismo, y durante un periodo determinado, 1826-1929, presentes en la Oficina Española de Patentes y Marcas (OEPM), organizando esta documentación para su posterior utilización por la comunidad científica. Para ello se han identificado y sistematizado las patentes referidas a la bicicleta, presentadas entre 1826 y 1929, realizando tablas de frecuencia que permitan extraer datos de su incidencia en la invención en el periodo considerado. Ello ha permitido conocer una serie de datos de los inventores, que, en definitiva son los creadores del desarrollo tecnológico en este campo, extrayendo, ordenando y categorizando la información sobre lugar de origen, tipo de inventor (empresa o particular), sexo, práctica de colaboración y profesión. Finalmente se ha estudiado el tipo de inventos, mostrando los sectores en los que se producen las invenciones, identificando si se han puesto en práctica, y determinando aspectos tales como su carácter de invención incremental, su posible consideración como invento raro y curioso, y su coexistencia con una marca registrada. El trabajo se inicia con la introducción seguida de un apartado en el que se presenta el marco teórico en el que se desarrolla la investigación, en una doble vía: en primer lugar el contexto de los documentos de patente, su relación con la innovación y su utilidad como fuentes de información, y en segundo lugar el marco de la invención en el ciclismo, presentando las fases esenciales de la evolución de la bicicleta (capítulo 2). En el marco metodológico (capítulo 3) se explican fuentes y metodología, presentando a continuación el diseño de la investigación, que se resume como sigue: 1- Determinación del universo de datos, 2- Consulta en el Archivo Histórico de la OEPM, 3- Diseño y creación de la base de datos propia, 4- Consulta de los expedientes y toma de imágenes, 5- Tratamiento y análisis de los datos, 6- Búsqueda de información en fuentes para patentes extranjeras, y 7- Consulta a la base de datos de Marcas de la OEPM. El capítulo 4 está dedicado a la investigación propiamente dicha, estructurado en tres grandes bloques. El primero recoge las cuantificaciones tabuladas del total de patentes y el análisis de determinados aspectos generales como la cronología de la invención y diversas comparaciones con resultados obtenidos en otros trabajos. El segundo bloque está centrado en los estudios de solicitantes de patentes, protagonistas de las invenciones. De ellos se contemplan una serie de datos extraídos de los expedientes, y posteriormente tabulados y cuantificados: su procedencia geográfica, su adscripción como empresas o solicitantes particulares, y sus datos de colaboración, finalizando el bloque con un apartado que dedicamos a la innovación femenina, que consideramos una línea de investigación interés. El tercer bloque, el más amplio de todos, está dedicado a la descripción y análisis de los datos referidos a los propios inventos, puesto que es la aplicación de los inventos lo que marca el desarrollo tecnológico de la máquina bicicleta, y su consiguiente evolución histórica y social. Se estructura asimismo en varias secciones. La primera es la más amplia, donde se muestran y explican los datos que tienen que ver con la adscripción de los inventos a sectores temáticos, es decir, que desarrolla las funciones o componentes de la bicicleta que han sido objeto de invención. Los apartados siguientes muestran datos y consideraciones sobre las patentes puestas en práctica, las invenciones incrementales, los inventos curiosos, y las patentes con posible marca registrada de su nombre. Finalmente, las conclusiones del estudio, el establecimiento de posibles líneas abiertas de investigación, la relación de fuentes consultadas y los anexos cerrarán la exposición de esta tesis. ABSTRACT The main goal of this research thesis is to shed light on a specific documentary record: patents presented in Spain, regarding a specific theme: bicycles and cycling, within a given period: 1826-1929. This record is organized for the ulterior use by the scientific community. In order to carry out this goal, the mentioned patents have been identified and systematized, and analyzed for frequency in order to infer the incidence of its invention in the period under consideration. This has brought to light some information on the inventors which are, after all, the creators in the technological development of that field. Their bibliographical information: origin, type of inventor (company or individual), gender, collaboration behavior and profession. Finally, the type of inventions has been studied, showing the sectors in which inventions are produced, whether these were transferred to practice, and other key information like the incremental nature of their invention, their possible consideration as ‘rare or curious invention’, and their coexistence with a registered trademark. This thesis is organized with an initial introduction, after which a section outlines the theoretical framework for the research along two axes: first the context of the patent documents, their relation with innovation and their usefulness as information sources; second, the invention of cycling and the development phases of bicycles. In the methodological section the sources and methodology are explained and reasoned, followed by the research design: 1-determination of the data universe, 2-consultation at the historical archive of the OEPM (National Patent Office), 3-design and creation of a database, 3-analysis of the files and image catchment, 5-treatment and analysis of data, 6-browsing of source information for foreign patents, and 7-consultation of the trademark information at the OEPM. Chapter 4 is dedicated to research itself, in three main sections. The first one has the quantification of the patent total in tables and the analysis of specific overall chronological aspects of the invention, and some comparisons with the results obtained in other research. The second section is centered on the studies of patent requests and inventors. Some data extracted from the files has been systematized: geographical origin, adscriptions as companies or individuals, and their collaboration data, ending with a sub-section on women’s invention, which we consider an interesting research line. The third section, the biggest one of them all, is dedicated to the description and analysis of the data referred to the inventions themselves, because it is the application of the inventions which constitutes the technological development of the bicycle, and therefore its historical and social evolution. It is also structured in various sub-sections. The first one is the longest one, with information regarding the thematic typology of the inventions: functions and bicycle components which are innovated. The other ensuing subsections study patents which were actually incorporated and used, incremental inventions, curious inventions and patents with possible associated trademarks. Finally, the study conclusions, the establishment of lines of potential further research, the references used, and the annexes which culminate the thesis exposition.

Local optimal scale in a hierarchical segmentation method for satellite image: an OBIA approach for the agricultural landscape

Overrecentdecades,remotesensinghasemergedasaneffectivetoolforimprov- ing agriculture productivity. In particular, many works have dealt with the problem of identifying characteristics or phenomena of crops and orchards on different scales using remote sensed images. Since the natural processes are scale dependent and most of them are hierarchically structured, the determination of optimal study scales is mandatory in understanding these processes and their interactions. The concept of multi-scale/multi- resolution inherent to OBIA methodologies allows the scale problem to be dealt with. But for that multi-scale and hierarchical segmentation algorithms are required. The question that remains unsolved is to determine the suitable scale segmentation that allows different objects and phenomena to be characterized in a single image. In this work, an adaptation of the Simple Linear Iterative Clustering (SLIC) algorithm to perform a multi-scale hierarchi- cal segmentation of satellite images is proposed. The selection of the optimal multi-scale segmentation for different regions of the image is carried out by evaluating the intra- variability and inter-heterogeneity of the regions obtained on each scale with respect to the parent-regions defined by the coarsest scale. To achieve this goal, an objective function, that combines weighted variance and the global Moran index, has been used. Two different kinds of experiment have been carried out, generating the number of regions on each scale through linear and dyadic approaches. This methodology has allowed, on the one hand, the detection of objects on different scales and, on the other hand, to represent them all in a sin- gle image. Altogether, the procedure provides the user with a better comprehension of the land cover, the objects on it and the phenomena occurring.

Superpixel-based roughness measure for multispectral satellite image segmentation

The new generation of artificial satellites is providing a huge amount of Earth observation images whose exploitation can report invaluable benefits, both economical and environmental. However, only a small fraction of this data volume has been analyzed, mainly due to the large human resources needed for that task. In this sense, the development of unsupervised methodologies for the analysis of these images is a priority. In this work, a new unsupervised segmentation algorithm for satellite images is proposed. This algorithm is based on the rough-set theory, and it is inspired by a previous segmentation algorithm defined in the RGB color domain. The main contributions of the new algorithm are: (i) extending the original algorithm to four spectral bands; (ii) the concept of the superpixel is used in order to define the neighborhood similarity of a pixel adapted to the local characteristics of each image; (iii) and two new region merged strategies are proposed and evaluated in order to establish the final number of regions in the segmented image. The experimental results show that the proposed approach improves the results provided by the original method when both are applied to satellite images with different spectral and spatial resolutions.

URIs and Intertextuality: Incumbent Philosophical Commitments in the Development of the Semantic Web

Examines two commitments inherent in Resource Description Framework (RDF): intertextuality and rationalism. After introducing how rationalism has been studied in knowledge organization, this paper then introduces the concept of bracketed-rationalism. This paper closes with a discussion of ramifications of intertextuality and bracketed rationalism on evaluation of RDF.
